Contaminated Media Forum

DEP's Contaminated Soils Forum was originally established in 1998 to provide an open forum for external and internal interested parties. In response to numerous requests, the forum has been re-established and renamed Contaminated Media Forum (CMF) to provide that open forum and to come to consensus on how to apply the lessons learned from Risk Based Corrective Action (RBCA) implementation over the last several years.

The CMF provides a shared venue for interested parties to discuss a variety of topics. Areas of discussion include evolving policy, scientific, and rule application issues associated with contaminated site cleanup and re-use, using risk-based management principles. Topics and presentations are intended to generate discussion and promote consideration of ideas and options, and do not represent policy or operational positions. The CMF discussions supplement the collaborative decision-making process and foster improved regulatory practices that provide responsible environmental protection while facilitating compliance and minimizing regulatory burden.

Probabilistic Risk Assessment Subgroup

• The recent changes to Chapter 62-780, F.A.C., to clarify the requirements for preparing Probabilistic Risk Assessments (PRAs) has led to the formation of a new subgroup of the Contaminated Media Forum to discuss issues regarding parameters and input assumptions for PRAs. Specific topics discussed:
  • Testing the reliability of back-calculated outputs (run forward calculations to see if results match)
  • PRAs based upon both variability and uncertainty distributions and 2D-PRA approaches
  • Distributions (uniform, triangular, etc.) based on professional judgment due to lack of available data
  • Distributions for toxicity values and toxic equivalency factors
  • Exposure start age, and focus on protection of children for other exposure factors
  • Relative bioavailability (literature-based variability distributions versus site-specific bioavailability studies)
  • Adjusting the soil ingestion distribution
